This read-only enumerated integer, part of the EZ2Boost router table, indicates whether a given boosted-router entry was learned dynamically or configured statically; the source description is empty, so this is inferred from the object's name and its enumeration values. An admin checks this to distinguish routers the device auto-discovered via EZ2Route from ones an administrator manually added. For example, seeing dynamic(1) for an entry confirms the device learned about that router automatically rather than through manual configuration.
